The latest weather forecast doesn't come from Dublin, London or New York — it comes from deep space, where a lonely world drifts without a sun and glows with auroras more dazzling than Earth's northern lights.
The world, called SIMP-0136, is about 200 million years old and lies about 20 light-years away in the constellation Pisces. It isn't quite a world nor a star. Astronomers classify it as a brown dwarf, sometimes dubbed "failed stars." Like stars, this world forms from collapsing clouds of gas, but it never grows massive enough to sustain hydrogen fusion in its core — the defining trait of a star.
